摘要： A heating apparatus comprises a plastic body and a planar heating element, together defining a liquid heating vessel. The heating element is clamped between a portion of the body and a retaining ring, the body and the retaining ring being fixed together by an induction weld. Uniform compression of a seal is obtained during the welding process. The weld provides a reliable seal.
